README

Data Limit (dalim)

🇮🇩 Bahasa Indonesia? Baca → indonesia.md

Track your data usage on Android and automatically enforce a budget you configure: daily, weekly, or monthly. The interface is bilingual — switch between English and Bahasa Indonesia in the app's LANGUAGE setting.

A normal app cannot kill the mobile radio. When the limit is hit the app locks the whole screen with a full-screen data gate — over whatever app you're in — until you explicitly allow more data.

Download

Latest build is a production release, signed with the release keystore. Install on Android 8.0+ (API 26).

Version	Type	Download
`v0.3.1`	Production · signed	datalimit-0.3.1-signed.apk

Release page (anchor to tag): github.com/arlingkin/dalim/releases/tag/v0.3.1
Checksum: SHA256SUMS.txt

Earlier testing builds (v0.2.x-pre, unsigned / debug-signed) are still available on the releases page.

Features

Area	Details
Budget types	Daily · Weekly · Monthly
Window styles	Fixed (midnight reset) / Rolling 24 h
Dashboard	Used / Limit / Remaining gauge, RX & TX, last check time
Gate	Full-screen blocking overlay over any app + re-popping full-screen alert, "+100 MB" escape hatch
Autostart	Monitoring resumes after reboot
Permissions	One-tap flow for Usage Access, Overlay, Notifications
Language	English · Bahasa Indonesia (in-app switch)

Permissions explained

Permission	Why
`PACKAGE_USAGE_STATS`	Read exact mobile/Wi-Fi totals
`SYSTEM_ALERT_WINDOW`	Show the blocking data-gate overlay
`POST_NOTIFICATIONS`	Display high-priority alerts
`FOREGROUND_SERVICE` + `dataSync`	Keep the counter running in background
`RECEIVE_BOOT_COMPLETED`	Auto-start monitoring after reboot

Building locally

# Requires Android SDK (Android Studio is the easiest way)
./gradlew :app:assembleDebug
# output: app/build/outputs/apk/debug/app-debug.apk

Or run gradle wrapper --gradle-version 8.7 first to generate gradlew.

To build a signed release you need the release keystore and its credentials (they are injected as DALIM_KEYSTORE_* environment variables — never committed):

export DALIM_KEYSTORE_FILE=/path/to/dalim-release.jks
export DALIM_KEYSTORE_PASSWORD=...
export DALIM_KEY_ALIAS=dalim
export DALIM_KEY_PASSWORD=...
./gradlew :app:assembleRelease
# output: app/build/outputs/apk/release/app-release.apk

CI / Release

Every push to main (or manual Run) builds a signed release APK via GitHub Actions, using the release keystore restored from repository secrets (DALIM_KEYSTORE_RELEASES plus DALIM_KEYSTORE_PASSWORD, DALIM_KEY_ALIAS, DALIM_KEY_PASSWORD), and publishes it as a full GitHub release (v0.3.1 and later) with a SHA256SUMS.txt checksum.

Roadmap

Optional root/system module to actually disable the radio
Per-app data breakdown
Alerts at 80 % / 90 %
Scheduling (e.g. "weekend unlimited")
Export/import of configuration
